Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outer wall refreshing method.

[0002]

2. Description of the Related Art The inventors of the present invention have previously proposed a refreshing method for renewing an outer wall of an existing building by directly adhering an outer wall material having a necessary exterior coating to the outer wall surface of the existing building. Invented a construction method called "Japanese Patent Application No. 6-10
Filed as No. 1808.

According to the construction method according to this patent application, large-scale construction is not required as compared with the conventional construction method, and the necessary surface coating is performed in advance in the factory. Therefore, a new coating is applied to the existing outer wall surface. There is a great advantage over the ones that do not need to consider measures for scattering paint and odors in the neighborhood.

[0004]

However, in such a conventional refreshing method, in addition to a method of directly bonding the outer wall material, in any case, the area to the extent of simply reforming the outer wall surface is obtained. Rather, it did not improve the habitability of the house. In particular, a building that requires such a reform of the outer wall is an old building that has been built for more than 10 years, and therefore, in terms of the heat insulating property of the building, etc., it is far more than the current building. There is a problem of being inferior.

In view of the above points, the present invention is not limited to merely reforming the outer wall surface, but also improves the functionality of the outer wall so that the habitability can be improved at the same time. The purpose is to provide a refreshing method.

[0006]

In order to solve the above problems, according to the present invention, an outer wall panel having a heat insulating material of a required thickness on the back surface of a siding material forming a new outer wall surface is provided on the surface of an existing outer wall. Characterized by direct bonding.

Further, in the above, as a method for adhering the outer wall panel, an outer wall panel provided with a heat insulating material of a required thickness on the back surface of the siding material forming a new outer wall surface,
What is characterized in that the adhesive is applied to a plurality of places so that the back surface of the heat insulating material is coated, and the adhesive is also applied along the periphery of the heat insulating material to adhere to the surface of the existing outer wall. Provided.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a drawing showing a method for adhering outer wall panels according to the present invention. As shown in FIG. 1, a new outer wall is added to an old outer wall surface (1) of an existing building such as a house or an apartment. By directly adhering the panel (2), the design of the outer wall surface is renewed.

As shown in FIG. 2, the outer wall panel (2) has a siding material (3) with a thickness of about 5 mm, which has a design pattern and a coating on its surface, for example, an embossed pattern surface. Then, the siding material (3) to which the heat insulating material (4) having a required thickness, for example, a thickness of about 30 mm, is previously adhered is used on the back surface side. As the heat insulating material (4), for example, a hard expanded polystyrene resin or the like is used. The outer wall panel (2) thus formed in advance is coated with the adhesive (5) on the back surface side of the heat insulating material (4) so as to be placed in several places as shown in FIG. Similarly, the adhesive (5) is applied to the four circumferences of the material (4) in a bead shape, and this is directly adhered to the outer wall surface (1) for construction.

FIG. 3 is a sectional view of a joint portion of the outer wall to which the outer wall panel (2) is adhered. In the figure (7)
(7) is a framed pillar of an existing building made of channel steel,
Existing outer wall panels (8) (8) of the building are similarly attached to the outer surfaces of the frame support columns (7) (7). These existing outer wall panels (8) include an iron frame (9) having a U-shaped cross section, and a siding material (10) attached to the surface side of the iron frame (9),
Similarly, a back plate (11) attached to the back side and a heat insulating material (12) filled between the siding material (10) and the back plate (11).
This outer wall panel consists of the iron frame (9)
A concave portion (13) is formed at the left and right ends of (8).

In a joint portion between the existing outer wall panels (8) and (8), a joint sheet (14) is attached in advance across the outer surfaces thereof, and a new outer wall panel (2) (2) is adhered thereto. doing. Further, after inserting the heat insulating material (17) into the joint portion between the new outer wall panels (2) (2), a pair of fins are provided on both sides.
A joint material (16) made of a synthetic resin provided with (15) is filled from the outside.

FIG. 4 shows an example of the structure of the joints of the corners of the entering corner. In the corners of the entering corner, existing outer wall panels (8) adjacent to each other at right angles with the corners sandwiched therebetween.
L along the inside corner so that it extends over the surface of (8)
Glue the attachment plate (18) made of letter-shaped metal iron plate, and attach the attachment plate (1
The joint sheets (14) and (14) similar to those described above are attached across the end of 8) and the surface of each outer wall panel (8). And
Adhere new outer wall panels (2) (2) to these surfaces.

Further, in this corner portion, new outer wall panels (2) (2) adjacent to each other with the corner interposed therebetween.
One of the outer wall panels (2) is extended to the extended portion of the end face of the other outer wall panel (2) to form a one-sided winch structure, and between the extended outer wall panel (2) outer surface and one outer wall panel (2) end face. The same heat insulating material (19) as described above is inserted and the joint material (16) is filled.

FIG. 5 shows the structure of the upper end portion of the new outer wall panel (2) on the eaves back side. In this eaves back portion, the upper end of the new outer wall panel (2) and the eaves back plate (20). A relatively large gap is provided between the outer wall panel (2) and the outer surface of the outer wall panel (2) to facilitate the bonding work of the new outer wall panel (2). Attach the L-shaped metal parting material (21) that extends over the upper ends of the siding material (3) and the heat insulating material (4) to the adhesive (2
2) Adhesive with (22) to improve the design of this part.

In FIG. 5, (23) is the eaves back plate (20).
This is an existing eaves back parting member provided so as to span between the outer surface of the upper end portion of the existing outer wall panel (8). Such a parting material (21)
Is installed not only on the back of the eaves but also around the opening, the bottom of the panel, etc. to improve the external appearance and protect the heat insulating material (4).

[0016]

According to the present invention, since a new outer wall panel is directly bonded to an existing outer wall, no large-scale construction is required, and it is not necessary to take measures against scattering of paint and odors in the neighborhood. In addition to the above effect, the siding material is pasted with a heat insulating material of the required thickness in advance and is adhered to the existing outer wall surface. This has the effect of improving the habitability without stopping.
